DETAILED DESCRIPTION

The following is a description of exemplary hitch guide assemblies andcomponents thereof. The embodiments described herein are exemplary innature and are not intended to be limited in structure or application.

As used in this specification and the appended claims, the articles “a,”“an,” and “the” include plural referents unless expressly andunequivocally limited to one referent.

FIG. 1 is a perspective view of an exemplary hitch guide assembly. Incertain embodiments, the hitch guide assembly comprises guide member 2,main support body 8, and a guide mechanism. As shown in FIG. 1, theguide mechanism may comprise hinge arm 10 and push arm 18.

In certain embodiments, the main support body comprises an elongatedbody extending vertically. FIG. 3 is a perspective view of exemplarymain support body 8, which comprises slide bar 7, bottom plate 20, guidemember stop 30, and pivot connectors 22 and 23. In certain embodiments,the slide bar may be constructed out of flat iron stock (e.g.,2″×¾″×8½″). The bottom plate may be constructed from the same piece ofstock as the slide bar, wherein the bottom plate is formed by bendingthe stock to form an L-shape (e.g., 80° angle). In certain embodiments,the bottom plate may be constructed out of flat iron stock (e.g.,3″×2″×¾″) that is welded to the slide bar. In certain embodiments,bottom plate 20 may be constructed to define aperture 28. In certainembodiments, pivot connectors 22 and 23 may be created by weldingthreaded studs on the bottom plate or at the point at which the bottomplate and slide bar connect.

As shown in FIG. 4, guide member 2 comprises guide plates 4 and 5, backstop 34, guide member connectors 26 and 27, and slide channel 6. Incertain embodiments, slide channel 6 is constructed to define slidechannel opening 32. Guide member 2 comprises a unitary body, whereinguide plates 4 and 5 define a wedge (or V) shape. In certainembodiments, the guide plates may be connected to each other directly bya weld or bend, without a back stop. However, guide member 2 includesback stop 34 positioned between guide plates 4 and 5, which mayconnected by a weld or a bend in the same piece of material. In certainembodiments, the guide member may be defined by a particular width(e.g., 10″) and height (e.g., 3¾″). Each guide plate may be constructedfrom similar pieces of flat steal or iron stock (e.g., ¼″×6″×3¾″). Thedimensions of the back stop may also be constructed from similarmaterials (e.g., 2″×3¾″). Slide channel 6 is connected to the wedge viathe back side of back stop 34. In certain embodiments, the slide channelmay be formed out of steel or iron stock, wherein the slide channeldefines an opening having dimensions (e.g., 1″×2″×3¾″) appropriate forreceiving at least a portion of the main support body (e.g., slide bar7). The guide member connectors may be constructed from threaded studswelded to each side of the slide channel.

As shown in FIG. 6, exemplary hinge arm 10 may comprise arch 38,proximal straight stretches 12 and 13, pivot collars 40 and 41, distalstraight runs 16 and 17, and hinge arm connectors 24 and 25. In certainembodiments, the hinge arm may be constructed from an iron rod (e.g.,about 3/8″) bent at a 180° angle to form a U-shaped arch (e.g., arch38). In certain embodiments, the resulting U-shaped structure definestwo proximal straight stretches (e.g., about 2½″) and extends downwardat an angle (e.g., about 70°) for a distance (e.g., about 2″). Thestraight stretches may then be bent upward at an angle (e.g., about 90°)and extend into distal runs for a distance (e.g., about 3″).

As noted above, the guide mechanism may comprise a hinge arm and a pusharm. Reference to the “proximal end” of the guide mechanism generallyrefers to portions of the guide mechanism positioned in front of themain support body. For example, with reference to FIGS. 1 and 6, the“proximal end” of the guide mechanism would be represented by the arch38 and proximal straight stretches 12 and 13. On the other hand,reference to the “distal end” of the guide mechanism generally refers toportions of the guide mechanism positioned behind the main support body.For example, with reference to FIGS. 1 and 2, the “distal end” of theguide mechanism would be represented by distal straight runs 16 and 17,and push arms 18 and 19. In certain embodiments, the proximal end of theguide mechanism is adapted to allow engagement of the trailer hitch withthe vehicle tow hitch. That is, in certain embodiments, the proximal endof the guide mechanism is shaped to allow for the simultaneous:application of force to the guide mechanism; and engagement (e.g.,connection) of the trailer hitch to the hitch point (e.g., ball hitch)of the vehicle tow hitch. In certain embodiments, as demonstrated in thefigures, this may accomplished by providing a hinge arm that surroundsat least a portion of, or is in close proximity with, the ball hitch.

FIG. 5 illustrates an exemplary structure of a push arm, which definesapertures 36 and 37. Push arms may be constructed from flat iron stockand, in certain embodiments, may measure about 4″ long and about 1/8″thick.

In certain embodiments, the hitch guide assembly is adapted to direct atrailer hitch to a vehicle tow hitch. In addition, the hitch guideassembly may protect the back of the tow vehicle from the trailer hitchas the operator backs the tow vehicle in an attempt to connect thetrailer to the vehicle tow hitch. Accordingly, in certain embodiments,the hitch guide assembly is adapted to connect to the tow vehicle. Incertain embodiments, the hitch guide assembly and the vehicle tow hitchare constructed as part of a single unit. In other embodiments, thehitch guide assembly is adapted to attach to a tow vehicle via a vehicletow hitch. In certain embodiments, the vehicle tow hitch comprises avehicle mount and a hitch point. The vehicle mount represents theprimary structure that connects a trailer to the tow vehicle. The hitchpoint represents the point at which the trailer hitch engages andconnects to the vehicle tow hitch. An exemplary vehicle mount wouldinclude a tow stinger, while an exemplary hitch point would include aball hitch. In certain embodiments, the hitch guide assembly is adaptedto connect to the vehicle tow hitch by attaching the bottom plate of themain support body to the stinger via the hitch ball. As noted above,bottom plate 20 of main support body 8 may define aperture 28. Thus, incertain embodiments, the hitch guide assembly is adapted to connect to avehicle tow hitch by positioning the bottom plate between the hitch balland the stinger, wherein the bottom plate is held in place by passingthe hitch ball connection through the bottom plate aperture.

As noted above, in certain embodiments, both the guide mechanism and theguide member are mounted to the main support body. In certainembodiments, the guide mechanism comprises a hinge arm, which ispivotally mounted to the main support body. In certain embodiments, theguide member is slidably mounted to the main support body. In certainembodiments, the hinge arm comprises at least one proximal straightstretch and at least one distal straight run. In certain embodiments,the distal end of the guide mechanism comprises the at least one distalstraight run of the hinge arm, and at least one push arm. In certainembodiments, the distal end of the guide mechanism is engaged with theguide member. In certain embodiments, the distal end of the guidemechanism is connected (e.g., bolted) to the guide member.

With reference to the exemplary embodiments illustrated in FIGS. 1-6,hinge arm 10 is pivotally mounted to main support body 8 via pivotconnectors 22 and 23, and pivot collars 40 and 41. Guide member 2 isslidably mounted to main support body 8 by positioning slide bar 7within slide channel opening 32. Hinge arm 10 is connected to push arms18 and 19 via hinge arm connectors 24 and 25, respectively. Push arms 18and 19 are connected to guide member 2 by guide member connectors 26 and27, respectively. As shown in FIG. 5, the connections of push arms 18and 19 can be done through apertures 36 and 37.

Operation of one embodiment of a hitch guide assembly is exemplified inFIGS. 7 and 8. The tow vehicle may comprise bumper system 44 and vehicletow hitch 46. Vehicle tow hitch 46 comprises a vehicle mount and a hitchpoint, e.g., tow stinger 48 and ball hitch 50, respectively. The hitchguide assembly is connected to vehicle tow hitch 46 by bolting bottomplate 20 of the main support body between ball hitch 50 and stinger 48.Trailer hitch 52 of a trailer includes trailer tongue 54. Withparticular reference to FIG. 7, as the tow vehicle is backed up by theoperator in an effort to connect the trailer to the vehicle tow hitch,trailer tongue 54 (partially obscured by guide plate 4) is guided intoposition over hitch ball 50 by the wedge shape that is defined by guideplates 4 and 5 of guide member 2. Once in position, the operator maylower trailer hitch 52. As trailer hitch 52 is lowered, it contacts andapplies force to hinge arm 10.

With reference to FIG. 8, complete lowering of trailer hitch 52 by crankmechanism 56 simultaneously allows for: the engagement of trailer tongue54 with hitch ball 50; and the vertical displacement of guide member 2.Hinge arm 10 is hingedly connected to guide member 2 via one or morepush arms, including push arm 19. The application of external force tohinge arm 10 by trailer tongue 54 as the trailer is lowered allows forpivoting of hinge arm 10 about its connection to the main support bodyby the one or more pivot collars, including pivot collar 40. Thus, thepivoting of hinge arm 10 vertically displaces guide member 2 along slidebar 7 via the one or more push arms, including push arm 19. In certainembodiments, the vertical displacement of guide member 2 moves the guidemember out of the operating plane of trailer hitch 52.

In certain embodiments, movement of the guide member out of the plane ofthe trailer hitch may help to increase the turning radius of the towvehicle. For example, in certain embodiments, turning and/or sharpcornering by the tow vehicle may result in contact between the tow hitchand the guide member if both devices operate in the same horizontalplane. Accordingly, in certain embodiments, the hitch guide assemblydescribed herein allows for the displacement of the guide member outsideof the plane of operation of the tow hitch.

In certain embodiments, the guide member may be moved out of theoperating plane of the trailer hitch in a horizontal manner. Forexample, in certain embodiments, the hitch guide assembly is adapted toallow for the horizontal displacement of the guide plates. In certainembodiments, the horizontal displacement of the guide plates comprisesconverting the wedge-shape of the guide member into a planar shape.Exemplary hitch guide assemblies capable of horizontally displacing theguide member are illustrated in FIGS. 9 and 10, wherein the guideassembly includes main support body 60, hinge arm 10, guide membercomprising guide plates 62 and 64, slide channels 72 and 73 attached toguide places 62 and 64, respectively, and push arms 70 and 76. Mainsupport body 60 also includes slide bars 66 and 68, as well as uppertabs 69 and 71, and lower tab 78.

FIG. 11 illustrates main support body 60, which comprises bottom plate82, pivot connectors 22 and 23, and slide bars 66 and 68. In certainembodiments, bottom plate 82 is constructed to define aperture 84. Incertain embodiments, pivot connectors 22 and 23 may be created bywelding threaded studs on bottom plate 82. In certain embodiments, slidebars 66 and 68 may be created from pieces of round stock welded tobottom plate 82. Upper tabs 69 and 71, as well as lower tabs 78 and 80,may be cut from flat stock and welded to their respective slide bars.

FIG. 12 illustrates an exemplary push arm, which may be used for eitherof push arms 70 and 76. The push arm of FIG. 12 includes main arm 86,which defines aperture 88. Flange 90 is connected to the main arm 86,and defines slotted aperture 92. In certain embodiments, main arm 86 andflange 90 may be created from a single piece of flat stock that isshaped to provide the appropriate structure. Alternatively, flange 90can be created from a separate piece of material that is welded to mainarm 86.

FIGS. 13 and 14 illustrate an exemplary slide channel, which may be usedfor slide channels 72 and 73. As noted above, a slide channel may beindependently connected to each of the guide plates. For example, slidechannels 72 and 73 may be welded to guide plates 62 and 64,respectively. The exemplary slide channels are shaped to define uppercurvature 102 and lower curvature 104. In certain embodiments, the slidechannels will each comprise at least one notch. In certain embodiments,the slide channels will each comprise at least two notches. For example,the slide channel illustrated in FIG. 13 comprises upper notch 94 andlower notch 96. Upper notch 94 and lower notch 96 are offset, and areadapted to allow for engagement with the upper and lower tabs on a slidebar. For example, with reference to the figures, slide bar 66 may bepositioned within the slide channel via slide channel opening 100, suchthat bottom notch 96 and top notch 94 are shaped to allow for engagementwith lower tab 78 and upper tab 69, respectively, as the slide channelmoves along slide bar 66. The flange of push arms 70 and 76 may beconnected to their respective slide channels via guide member connector98 and slotted aperture 92.

As with the hitch guide assemblies of FIGS. 1 and 2, the hitch guideassemblies of FIGS. 9 and 10 may be attached to a vehicle tow hitch viabottom plate 82 and aperture 84. In the resting state, guide plates 62and 64 form a wedge shape, which is held rigidly in place by theengagement of the bottom notches of slide channels 72 and 73 with thelower tabs of slide bars 66 and 68. The hitch guide assembly may beoperated by applying external force against the proximal end of U-shapedhinge arm 10, which is pivotally mounted to main support body 60, andhingedly connected to slide channels 72 and 73 via hinge arms 76 and 70,respectively. Force applied by the push arms against the slide channelsmoves the slide channels, and the guide plates connected thereto,vertically along slide bars 66 and 68. Engagement of upper curvature 102of the slide channel with an upper tab allows for rotation of the slidechannel about the axis of the slide bar. The simultaneous rotation ofthe slide channels about the axis of each slide bar allows for openingof the wedge shape by horizontally displacing the guide plates 62 and64. Engagement of the top notches with upper tabs 69 and 71 locks theguide member into an “open” configuration, wherein guide member 62 and64 take on a planar shape. Thus, in certain embodiments, the hitch guideassembly is adapted to simultaneously displace the guide member in ahorizontal and vertical manner. Slotted aperture 92 in the push armsallows for the free movement of guide member connector 98 as the slidechannels rotate about their respective slide bars.

The removal of force from hinge arm 10 (e.g., disengaging a trailerhitch) allows for the hitch guide assembly to return to its restingstate. The top notches of the slide channel will disengage from uppertabs 69 and 71. Engagement of lower curvature 104 of the slide channelwith a lower tab allows for rotation of the slide channel about the axisof the slide bar. The simultaneous rotation of the slide channels aboutthe axis of each slide bar allows for the closing of the guide platesand the return of the guide member to a wedge shape. Engagement ofbottom notches with lower tabs 78 and 80 locks guide plates 62 and 64back into the wedge shape.

The foregoing descriptions and embodiments have been provided forpurposes of illustration. They are not intended to be exhaustive orlimit the scope of what is described and/or claimed herein.
